Description

Technical Field

[0001] The invention relates to the technical field of surgical instrument disinfection, and in particular to a burn wound repair surgical instrument disinfection device. Background Art

[0002] Surgical instrument disinfection devices are devices used to clean, disinfect and sterilize surgical instruments. Such devices play a vital role in the medical field because they can effectively eliminate potential pathogens and ensure the safety and effectiveness of surgical operations. Physical disinfection methods include thermal disinfection (such as high-temperature steam or hot water) and radiation disinfection (such as ultraviolet light or ionizing radiation). These methods are generally suitable for non-cutting surgical instruments. Chemical disinfection methods include the use of chemicals such as chlorides, hydrogen peroxide, and aldehydes for disinfection. This method is effective, but you must pay attention to choosing a suitable disinfectant and follow the instructions. Gas disinfection methods include the use of gases such as ethylene oxide for penetrating sterilization, which can kill bacteria, viruses and fungi, but the concentration and duration of action must be strictly controlled when used. After the burn wound repair surgery is completed, the surgical instruments need to be disinfected, including the use of immersion to remove impurities remaining on the surface of the surgical instruments.

[0003] For example, the utility model patent with announcement number CN220293883U provides a surgical instrument disinfection device. When the surgical instruments need to be dried, the surgical instruments are placed on the drain pan, and the water on the surgical instruments leaks from the drain pan to the water collection pan to prevent water from accumulating at the bottom of the surgical instruments. When the surgical instruments were disinfected, a batch of surgical instruments were randomly piled on the drain pan, resulting in overlapping surgical instruments and easy to have sterilization dead corners.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figures 1 to 11 As shown, a burn wound repair surgical instrument disinfection device provided by Embodiment 1 of the present invention comprises a disinfection barrel 100, a disinfection rack 300 and a transfer mechanism. The disinfection barrel 100 is vertically arranged, the disinfection rack 300 is arranged in the disinfection barrel 100, and an annular placement plate 310 is fixedly arranged on the disinfection rack 300. The annular placement plate 310 and the disinfection barrel 100 are coaxially arranged. There are multiple annular placement plates 310, and the multiple annular placement plates 310 are sequentially distributed along the up and down direction.

[0039] The transport mechanism includes a fixed rod 500, a transport assembly and an adjustment assembly. The fixed rod 500 is arranged in the sterilizing cylinder 100 so as to move up and down, and the fixed rod 500 can rotate along its own axis. The fixed rod 500 and the sterilizing cylinder 100 are coaxially arranged, the fixed rod 500 is located inside the annular placement plate 310, and the fixed rod 500 rotates clockwise by a first preset angle each time.

[0040] The transport assembly includes a sliding sleeve 610, a rotating frame 410 and a transmission unit. The sliding sleeve 610 is slidably arranged on the outside of the fixed rod 500, and the sliding sleeve 610 and the fixed rod 500 are coaxially arranged and rotate synchronously. The sliding sleeve 610 has a first position and a second position, and the first position of the sliding sleeve 610 is located above the second position. In the initial state, the sliding sleeve 610 is in the first position.

[0041] The rotating frame 410 is rotatably disposed on the sliding sleeve 610. The rotating frame 410 and the sliding sleeve 610 slide up and down synchronously. The rotating frame 410 and the sliding sleeve 610 cooperate with each other in a one-way ratchet manner. The sliding sleeve 610 can drive the rotating frame 410 to rotate clockwise synchronously, and the rotating frame 410 can rotate clockwise relative to the sliding sleeve 610.

[0042] In the initial state, the surgical instrument is placed on the rotating frame 410, and the transfer unit is used to transfer the surgical instrument from the rotating frame 410 to the annular placement plate 310. The weight of the surgical instrument has a first weight range and a second weight range, and the weight of the first weight range is less than the weight of the second weight range.

[0043] The transport mechanism has a first working state and a second working state. When the weight of the surgical instrument is within the first weight range, the transport mechanism is in the first working state. The first working state of the transport mechanism is that the sliding sleeve 610 is in the first position, and the sliding sleeve 610 drives the rotating frame 410 to rotate synchronously. The transport unit transports the surgical instrument from the rotating frame 410 to the annular placement plate 310.

[0044] When the weight of the surgical instrument is within the second weight range, the transport mechanism is in the second working state, and the second working state of the transport mechanism is that the sliding sleeve 610 first moves from the first position to the second position, and the adjustment component drives the rotating frame 410 to rotate clockwise by a second preset angle relative to the sliding sleeve 610. After the transport unit transfers the surgical instrument from the rotating frame 410 to the annular placement plate 310, the sliding sleeve 610 moves from the second position to the first position, and the adjustment component drives the rotating frame 410 to rotate clockwise by a third preset angle relative to the sliding sleeve 610.

[0045] The annular placement plate 310 is evenly divided into 360 degrees. When placing surgical instruments for the first time, the initial angle of the rotating frame 410 corresponds to 0 degrees of the annular placement plate 310, and the fixing rod 500 is at the upper end of the disinfection cylinder 100. The surgical instruments are placed on the rotating frame 410, and the fixing rod 500 drives the rotating frame 410 to move downward to the lowest annular placement plate 310, and then the surgical instruments are transported to the annular placement plate 310 through the transmission unit.

[0046] When the weight of the first surgical instrument being transported is within the first weight range, the sliding sleeve 610 continues to be in the first position, and the transport mechanism is in the first working state. The fixed rod 500 drives the rotating frame 410 to rotate synchronously clockwise by the first preset angle through the sliding sleeve 610, and the first surgical instrument is at the first preset angle. When the weight of the second surgical instrument being transported continues to be within the first weight range, the rotating frame 410 rotates the first preset angle again.

[0047] When the weight of the third surgical instrument being transported is within the second weight range, the sliding sleeve 610 moves from the first position to the second position, and the transport mechanism is in the second working state. The adjusting component first drives the rotating frame 410 to rotate clockwise by a second preset angle relative to the sliding sleeve 610. Therefore, at this time, the rotating frame 410 is driven by the fixed rod 500 to rotate the first preset angle, and the rotating frame 410 is rotated by a second preset angle relative to the fixed rod 500. Then, after the surgical instrument is placed on the annular placement plate 310, the sliding sleeve 610 moves from the second position to the first position again, and the adjusting component drives the rotating frame 410 to rotate clockwise by a third preset angle relative to the sliding sleeve 610. Then, when the weight of the fourth surgical instrument being transported continues to be within the second weight range, the rotating frame 410 first rotates by the first preset angle, then moves downward to rotate by the second preset angle, and finally moves upward to rotate by the third preset angle.

[0048] Between two adjacent surgical instruments, the angle between a surgical instrument in the first weight range and a surgical instrument in the first weight range is the first preset angle. The angle between a surgical instrument in the first weight range and a surgical instrument in the second weight range is the sum of the first preset angle and the second preset angle. The angle between a surgical instrument in the second weight range and a surgical instrument in the second weight range is the sum of the first preset angle, the second preset angle and the third preset angle.

[0049] The transfer mechanism can automatically adjust the angle between two adjacent surgical instruments according to the size of the surgical instruments. The intervals between surgical instruments of different sizes are different, the angle between two adjacent small-sized surgical instruments is the smallest, and the angle between two adjacent large-sized surgical instruments is the largest. On the basis of ensuring the maximum space utilization on the annular placement plate 310, it is ensured that sufficient space can be reserved between adjacent surgical instruments. There is no need for manual classification to prevent surgical instruments from overlapping each other, which leads to problems such as dead corners for disinfection, incomplete disinfection, and uneven disinfection.

[0050] In this embodiment, the rotating frame 410 includes a connecting ring 414 and a supporting plate 415. The connecting ring 414 is rotatably arranged on the outer side of the sliding sleeve 610.

The initial angle of the rotating frame 410 is 0 degrees, and the rotating frame 410 first descends to the annular placement plate 310 at the lowest end each time. When the sensor senses that the angle between the surgical instrument last placed on the annular placement plate 310 and the 360-degree position on the annular placement plate 310 is less than or equal to the sum of the first preset angle, the second preset angle and the third preset angle, the controller controls the distance of each extension of the first cylinder 110, so that the rotating frame 410 descends to the annular placement plate 310 last at the lower end when the surgical instrument is placed next time.

[0073] In this embodiment, a burn wound repair surgical instrument disinfection device further includes two cover plates 200 and two second cylinders 140. The two cover plates 200 are used to block the upper end of the disinfection cylinder 100. The second cylinder 140 is fixedly arranged on the disinfection cylinder 100, and the second cylinder 140 is arranged along the radial direction of the disinfection cylinder 100, and the extended end of each second cylinder 140 is fixedly connected to a cover plate 200.

[0074] Working process: start the second cylinder 140, the extended end of the second cylinder 140 contracts and drives the cover plate 200 to move, and after the two cover plates 200 move, the upper end of the disinfection cylinder 100 is opened, and disinfectant water is poured into the disinfection cylinder 100.

[0075] In the initial state, the sliding sleeve 610 is in the first position, the limit block is in the first slot 502, and the fixing rod 500 is at the upper end of the disinfection cylinder 100. The first protrusion 621 is arranged in the first inclined slot 505, and the second protrusion 631 is in the second vertical slot 701.

[0076] A surgical instrument is placed on the placement tray 460. When the surgical instrument is large and heavy, the placement tray 460 moves downward under the action of the first inclined surface, pressing the multiple movable side plates 450 to move in a direction gradually away from the axis of the connection tray 470. The area surrounded by the multiple movable side plates 450 is increased to accommodate larger surgical instruments and increase the stability of the surgical instrument on the placement tray 460. The support frame 440 is then placed on the multiple rollers 430, and the support frame 440 is on the side of the support plate 415 close to the fixed rod 500.

[0077] Afterwards, the first cylinder 110 is started, the extended end of the first cylinder 110 is shortened, and the motor 130 and the rotating shaft 900 are driven to move downward synchronously through the lifting frame 120, and the rotating shaft 900 drives the fixing rod 500 to descend synchronously, so that the fixing rod 500 is first located on the annular placement plate 310 at the lowest end, and when the sliding sleeve 610 is in the first position or the second position, the upper surface of the rotating frame 410 is slightly higher than the annular placement plate 310. The motor 130 is started, and the motor 130 drives the fixing rod 500 to rotate the first preset angle each time.

[0078] When placing the surgical instrument for the first time, the initial angle of the rotating frame 410 is 0 degrees. When the weight of the first surgical instrument to be transported is within the first weight range, the sliding sleeve 610 continues to be in the first position, and the transport mechanism is in the first working state. The fixed rod 500 drives the sliding sleeve 610 to rotate synchronously clockwise, and the sliding sleeve 610 drives the rotating frame 410 to rotate synchronously clockwise by the first preset angle through the first ratchet.

[0079] The fixing rod 500 drives the disassembly base 510 and the pre-tightening base 800 to rotate synchronously, and the disassembly base 510 drives the fixed outer ring 700 to rotate synchronously. Since the second protrusion 631 is in the first vertical groove 504, the fixed outer ring 700 drives the external rotating ring 630 to rotate synchronously clockwise. The external rotating ring 630 drives the internal rotating ring 620 to rotate synchronously through the third ratchet. The internal rotating ring 620 drives the first force storage ring 640 to rotate synchronously through the first telescopic rod 641, and the external rotating ring 630 drives the second force storage ring 650 to rotate synchronously through the second telescopic rod 651.

[0080] The water pump 420 is started, and the water pump 420 absorbs the disinfectant water in the disinfection cylinder 100 from the water inlet 422 and discharges it from the water outlet 421. The disinfectant water discharged from the water outlet 421 moves in the fourth chute 413. The disinfectant water drives the multiple impellers 431 to rotate, and then drives the multiple rollers 430 to rotate. When the rollers 430 rotate, the support frame 440 is driven to slide on the rollers 430. Until the support frame 440 is moved to the annular placement plate 310. Thus, the first placement of surgical instruments is completed.

[0081] Therefore, the rotating frame 410 rotates to the first preset angle following the fixed rod 500. Assuming the first preset angle is 10 degrees, the rotating frame 410 is at 10 degrees at this time, and the surgical instruments are placed at 10 degrees for the first time. Next, the first cylinder 110 is started, the extension end of the first cylinder 110 extends, and drives the fixed rod 500 to rise synchronously, so that the fixed rod 500 returns to the upper end of the sterilizing cylinder 100. At this time, the final angle of the rotating frame 410 when placed for the first time is 20 degrees.

[0082] Then, the next support frame 440 with the surgical instrument is placed on the rotating frame 410. When the surgical instrument is placed for the second time, the initial angle of the rotating frame 410 is 10 degrees. When the weight of the second surgical instrument is still within the first weight range, the rotating frame 410 continues to rotate by the first preset angle following the fixing rod 500. At this time, the final angle of the rotating frame 410 for the second time is 20 degrees, and the second surgical instrument is placed at 20 degrees.

[0083] When placing the surgical instrument for the third time, the initial angle of the rotating frame 410 is 20 degrees. When the weight of the third surgical instrument is within the second weight range, since the third surgical instrument is heavier, the sliding sleeve 610 overcomes the elastic force of the second spring, and the limit block is separated from the first slot 502, and the sliding sleeve 610 moves downward so that the limit block enters the second slot 503. The first spring 660 is stretched.

[0084] When the sliding sleeve 610 moves downward, it drives the inner rotating ring 620 and the outer rotating ring 630 to move downward synchronously. The first protrusion 621 on the inner rotating ring 620 slides in the first inclined groove 505, so that the inner rotating ring 620 rotates by a second preset angle, and the second preset angle is set to 5 degrees. When the outer rotating ring 630 moves downward, it drives the second protrusion 631 to slide in the first vertical groove 504, and the outer rotating ring 630 does not rotate at this time. Then, the first protrusion 621 enters the first vertical groove 504, and the second protrusion 631 enters the second inclined groove 702.

[0085] When the inner rotating ring 620 rotates, the rotating frame 410 is driven to rotate clockwise synchronously through the second ratchet, and the rotating frame 410 rotates relative to the fixed rod 500. Therefore, the rotating frame 410 rotates by the second preset angle relative to the fixed rod 500 after following the fixed rod 500 to rotate by the first preset angle. Therefore, the rotating frame 410 is at 35 degrees at this time, and the surgical instruments are placed at 35 degrees for the third time.

[0086] Afterwards, the transport unit is used to transport the surgical instruments for the third time from the rotating frame 410 to the annular placement plate 310. The weight on the rotating frame 410 becomes lighter, the first spring 660 is reset, the first spring 660 drives the sliding sleeve 610 to move upward, the sliding sleeve 610 returns from the second position to the first position, and the sliding sleeve 610 drives the rotating frame 410, the inner rotating ring 620 and the outer rotating ring 630 to move upward synchronously.

[0087] When the outer rotating ring 630 moves upward, the second protrusion 631 slides in the second inclined groove 702, thereby driving the outer rotating ring 630 to rotate clockwise by a third preset angle, and the third preset angle is set to 5 degrees. The outer rotating ring 630 drives the rotating frame 410 to continue to rotate clockwise by the third preset angle through the second ratchet. Therefore, after the third placement, the final angle of the rotating frame 410 is 40 degrees.

[0088] During this process, the first protrusion 621 slides in the first vertical groove 504, so the internal rotating ring 620 does not rotate. When the first protrusion 621 slides to the upper end of the first vertical groove 504 and enters the first horizontal groove 506. Under the action of the first spring 801, the first spring 801 causes the first power storage ring 640 to rotate clockwise, and the first power storage ring 640 drives the internal rotating ring 620 to rotate clockwise synchronously through the first telescopic rod 641, so that the first protrusion 621 slides in the first horizontal groove 506, and the first protrusion 621 enters the first inclined groove 505 in the next first slide groove. When the second protrusion 631 slides to the upper end of the second inclined groove 702 and enters the second horizontal groove 703. The second mainspring 802 causes the second force storage ring 650 to rotate clockwise, and the second force storage ring 650 causes the external rotating ring 630 to rotate clockwise through the second telescopic rod 651, and the second protrusion 631 moves in the second transverse groove 703, and the second protrusion 631 enters the second vertical groove 701 in the next second slide groove.

[0089] When placing the surgical instrument for the fourth time, the initial angle of the rotating frame 410 is 40 degrees. When the weight of the fourth surgical instrument is within the second weight range, the sliding sleeve 610 first moves downward to drive the rotating frame 410 to rotate the second preset angle relative to the fixed rod 500, and the first preset angle of the fixed rod 500 itself, so the rotating frame 410 is at 55 degrees at this time, and the surgical instrument is placed at 55 degrees for the fourth time. Then the sliding sleeve 610 causes the rotating frame 410 to continue to rotate the third preset angle. Therefore, the final angle of the rotating frame 410 for the fourth time is 60 degrees.

[0090] The initial angle of the fifth turret 410 is 60 degrees. When the weight of the fifth surgical instrument is within the first weight range, the final angle of the fifth turret 410 is 70 degrees.

[0091] Therefore, when the weight of the last surgical instrument is within the first weight range, the rotating frame 410 rotates 10 degrees when the weight of the next surgical instrument is within the first weight range. When the weight of the last surgical instrument is within the first weight range, the weight of the next surgical instrument is within the second weight range, or when the weight of the last surgical instrument is within the second weight range, the weight of the next surgical instrument is within the first weight range, the rotating frame 410 rotates 15 degrees. When the weight of the last surgical instrument is within the second weight range, the weight of the next surgical instrument is within the second weight range, the rotating frame 410 rotates 20 degrees.

[0092] When the sensor senses that the remaining position of the lowest annular placement plate 310 is less than or equal to 20 degrees, the controller controls the distance of each extension of the first cylinder 110, so that the rotating frame 410 is lowered to the upper annular placement plate 310 of the lower annular placement plate 310 during the next placement. When the disinfection is completed, the disinfection rack 300 is taken out, and all the support racks 440 are taken out.

[0093] The transfer mechanism can automatically adjust the angle between two adjacent surgical instruments according to the size of the surgical instruments. The intervals between surgical instruments of different sizes are different, the angle between two adjacent small-sized surgical instruments is the smallest, and the angle between two adjacent large-sized surgical instruments is the largest. On the basis of ensuring the maximum space utilization on the annular placement plate 310, it is ensured that sufficient space can be reserved between adjacent surgical instruments. There is no need for manual classification to prevent surgical instruments from overlapping each other, which leads to problems such as dead corners for disinfection, incomplete disinfection, and uneven disinfection.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
